Note: This analysis may be based on NTSB preliminary reports, which represent an initial, incomplete investigation. Facts can change as the investigation progresses, and preliminary findings should not be assumed to be accurate or final. For older events, a final NTSB report may have been issued β€” always consult the NTSB Aviation Query for the authoritative record.

NTSB Narrative

The student pilot reported that, while landing in a "strong" crosswind, the airplane touched down on the center line of the runway, but then veered hard to the left. He attempted to correct by using rudder and aileron inputs, but over corrected and the airplane veered sharply to the right and exited the runway. He applied full throttle to abort the landing; however, the airplane veered left across the runway, then continued off the left side of the runway. The airplane continued down an embankment, the nose impacted an "upslope" on the far side of a ditch and the airplane came to rest inverted.

The airplane sustained substantial damage to the empennage and both wings.

The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated weather observation system located about 1 mile from the accident site reported, about 15 minutes before the time of the accident, the wind was from 190Β° at 13 knots; and that about 15 minutes after the time of the accident, the wind was from 210Β° at 17 knots, gusting to 21 knots. The student pilot landed on runway 12R. The student pilot’s failure to maintain directional control while landing in gusting crosswind conditions.
